Abstract :
A nonlinear penalty threshold that contains the total nonlinear phase shift is examined as a criterion for scaling fiber optic links. We investigate 112 Gb/s PDM-QPSK hybrid optical networks consisting of either TrueWave (G.655) or AllWave (G.652) fiber. We establish experimental and simulation environments with robust absolute matching in both linear and nonlinear regimes. We identify both XPM and SPM penalties in 0% and 100% inline dispersion compensation schemes for the two different fiber types. Both experimental and simulation results reveal that 0% inline-compensated links operate with larger nonlinear threshold for increasing span count and readily yield simple design rules.
